Eliminate Trip Hazards and Stabilize Concrete Slabs

CRC Geotech uses TerraThane Hydrophobic Geotechnical Polyurethane Foam to raise or level concrete slabs, repel water and fill the voids beneath them. This process of raising concrete results in a repair which, when cured, is impervious to water. It is also environmentally friendly!  

Concrete Raising is also known as Poly Jacking, Mud Jacking, Concrete Lifting or Slab Raising.

CRC Geotech is a Certified TerraThane Geotechnical Polyurethane Installer.

Our engineered TerraThane Hydrophobic Geotechnical Polyurethane Foam is pumped under pressure into small holes drilled through existing concrete slabs. The foam displaces air pockets, repels water or water saturated materials that may be present, fills voids under the slab, raises the slab, and leaves a firm permanent subgrade.



What can be Slab Raised?

We can raise, level and stabilize sidewalks, curbs, gutters, streets, highways, parking lots, garage floors, patios, pool decks, industrial floors, bridge approaches, basketball courts. 

In essence, most any residential, commercial/industrial, and/or municipal concrete slab on grade can be raised, levelled and stabilized. Additionally, CRC can provide deep soil compaction, sewer and tunnel fill, and grout voids, abandoned pipes and cavities.

Why Slab Raising?

Customer Satisfaction - Cost! - The costs to raise or level concrete slabs are 50 to 75% LESS than the cost of concrete replacement.

Immediate Use - In most cases, concrete repaired through concrete raising can be used almost immediately following the completion of the job. In contrast, new or replaced concrete has to cure for a minimum of 28 days.

Long-term Fix - Concrete slabs raised with our cementitious slurry or polyurethane foam can carry a warranty of up to 2 years. The length of warranty depends on soil conditions, drainage and other factors.

No Disruption to Surrounding Landscape - No need to repair surrounding areas of grass, trees, and/or shrubbery as you would have to with concrete replacement.

Reduce Liability - Eliminate trip hazards, excessive step height, improper pitch of slabs.

No Environmental Impact - Green! - Landfill legislation in many parts of the country lists old concrete as Hazardous Waste, adding an additional recycling cost to those choosing to replace concrete (for both the operator and the customer).

Fixing Texas' Bridges - Making Bridges Great Again!

The CRC Geotech #TeamTerraThane Crew was busy raising a few approaches to box culverts using #TerraThane from #NCFI in order to protect those low profile tires and rims on your new Corvette!

Flash Flooding as well as water penetration through cracks and joints leads to erosion and settling of bridge approach slabs! We raised three bridge approaches on a Saturday!
